description: Turn coding, debugging, research, architecture, migration, deployment, or product work into a clear, evidence-backed technical post in an existing publishing system. Use when Codex should reconstruct primary evidence, decide whether the material deserves a note or article, align on the intended reader, choose among field-report, explainer, reversal, origin-story, hands-on, or evidence-led argument forms, write and edit the piece, inspect its rendered presentation, and publish it at the requested visibility. Pair with blog-system-design for changes to the shared blog system.

# AI Devblog

Write a technical story that changes what a particular reader understands,

believes, or can do. Keep the empirical honesty of a good engineering report,

but make comprehension and human interest the organizing priorities.

Use this order of attention:

> route the genre → align with the reader → choose the angle → explain →

> support with evidence → edit → cold-read → present → publish

For substantial work, read

[the human-writing review](references/human-writing-review.md) and

[the story modes](references/story-modes.md) before proposing an angle. Use

these writers as structural inspiration, not as personas to imitate.

Use `blog-system-design` with this skill when the task changes the shared blog

index, taxonomy, article shell, typography, navigation, search, responsive

behavior, or reusable components. A post must not silently redesign its

publication.

## Route the material

First decide whether a devblog is the right container:

- Put a routine shipped fact in a changelog or release note.

- Put durable project onboarding, commands, API guidance, and contributor

instructions in a README; use `ai-readme` when available.

- Put an exhaustive roadmap, product plan, design specification, API reference,

or component inventory in documentation.

- Continue here for reconstructed technical work, a tested argument, a

consequential origin story, or a mechanism worth teaching.

Apply an interestingness gate. A shipped capability alone is not enough. The

material needs at least one reader payoff: a non-obvious finding, consequential

decision, useful technique, measurable result, corrected belief, surprising

failure, illuminating mechanism, or reusable model. Recommend a smaller form

when the work does not earn a post.

Choose one primary story mode:

- **Field report:** a change, incident, migration, or measured result.

- **Short lab note:** one useful experiment, release, artifact, or strange fact.

- **Mechanism explainer:** a system made understandable through one example.

- **Incident or reversal:** a reasonable belief that reality disproved.

- **Evidence-led argument:** several concrete cases that revise a common belief.

- **Hands-on argument:** a stance earned through a small reproducible exercise.

- **Origin story:** turning points that explain why a system has its current

shape.

- **Product announcement:** what changed, why it helps, the hidden hard part,

and the exact constraint.

A post may borrow a secondary move, but do not turn every available fact into

an omnibus article. See [story modes](references/story-modes.md) for structures,

title families, and Dan Luu/Fly.io-inspired angle prompts.

Choose a weight that fits the idea:

- **Note:** about 300–800 words; one narrow finding and little ceremony.

- **Standard:** about 800–2,000 words; the default for a developed story.

- **Feature:** over 2,000 words only for a stated editorial reason; consider

splitting work that grows beyond roughly 4,000 words.

These are editing signals, not quotas. Never inflate a useful note or compress

a mechanism until it no longer makes sense.

## Align with the reader

Before a standard or feature post, determine what the skill user expects the

reader to **be**, **know**, and **want**. If this is not already explicit, ask

one compact batch in the `align-me` shape:

1. State each belief as a numbered decision.

2. Give lettered, mutually exclusive choices with concrete consequences.

3. Recommend one choice for each decision.

4. End with `Reply approve all to accept 1A, 2B, 3A, or give changes such as

2C.` Then wait.

Use [the reader-and-angle checkpoint](references/angle-review.md) for the exact

questions. Default to a smart adjacent engineer who knows the domain but not

the project and wants a useful mental model or decision. Do not ask what the

user has already answered. For a short note with an obvious readership, state

the inferred assumptions briefly and proceed.

Then write privately:

- **Before:** what the reader probably believes or cannot yet do.

- **After:** what the evidence should make them believe, understand, or try.

- **Spine:** the one question the post answers.

- **Not this post:** two or three tempting facts that belong elsewhere.

For a standard or feature post, offer two or three genuinely different angles

unless only one honest angle exists. Keep each option compact: title, promise,

and tradeoff. Recommend one and wait. Never hide a single thesis behind cosmetic

title variants.

## Establish the evidence boundary

Reconstruct the work before writing:

1. Inspect the relevant source, diff, issue, transcript, experiment, incident,

or primary external research.

2. Identify exact revisions, versions, data, configuration, dates, and

environment when they affect the claim.

3. Re-run or read the decisive tests and measurements when reasonably cheap.

4. Separate source change, commit, push or merge, deployment or migration, and

live user-facing verification.

5. Preserve failed attempts, unfavorable results, reversals, and uncertainty

when they explain the final conclusion.

6. Identify evidence that challenges the preferred thesis, especially for an

evidence-led argument.

Distinguish what this agent observed from repository history, another agent's

work, human decisions, and inference. Attribute material ideas and firsthand

observations. Do not invent motives, reactions, or a first-person experience.

When coding-agent threads exist, use them to recover the real prompt, surprise,

failed assumption, and decision sequence. Match a thread by commit, file,

command, and timestamp before using keyword similarity. Private threads may

inform causality, but quote or screenshot them only after checking disclosure,

secrets, identities, private paths, customer data, and internal architecture.

Use the minimum proof that changes a skeptical reader's mind. Judge evidence by

fit, directness, scope, freshness, and explanatory value. Link exact source,

official documentation, original issues or papers, tests, deployment records,

and public results near the claim they support. Put exhaustive logs, methods,

and provenance in a linked artifact or appendix.

Do not promote a green build, HTTP 200, commit, upload, or public URL into proof

of a different claim. Match numeric precision to the decision: round human

durations and measurements unless extra precision changes the conclusion.

## Address the elephant

Treat the title and deck as one honest promise. Choose the family that fits the

story: result, stance, reversal, distinction, paradox, mechanism, imperative,

question, or origin. Between the title, deck, and first paragraph, name the

central subject and stakes plainly.

If the post is about a Program Database, say `Program Database`. If it is about

SQLite, a product failure, a commercial interest, or a controversial

recommendation, say that. Do not bury the lede behind an abstract principle or

mystery hook. Cleverness may sharpen a clear subject; it may not conceal one.

Open according to the mode:

- use an artifact or consequence for a field report;

- use the disputed premise for an argument;

- use the visible result for a tutorial or lab note;

- use the admission and current consequence for a reversal;

- use the present constraint or decisive turn for an origin story.

Name the system and why it matters by the end of the first paragraph. State the

bottom line by the third. Label proposals and unshipped plans explicitly.

Follow the destination's existing front matter, author, avatar, and AI

assistance conventions. Do not invent a persona or add a new metadata model for

one post. Use a real publication date and a few durable, specific tags.

## Explain at the reader's altitude

Default to a smart adjacent engineer. Declare at most three concepts the post

may assume. Define project-specific nouns on first use and give plain behavior

before an abbreviation or formal term. A link may deepen an explanation; it

cannot replace one.

When the mechanism is unfamiliar or the draft makes a causal jump, use as many

of these rungs as the reader needs:

1. observable consequence;

2. smallest concrete example;

3. plain-language model;

4. precise technical term;

5. implementation detail;

6. important edge case.

The first three are the usual minimum. Skip a later rung when it does not help

the intended reader. Prefer one recurring request, row, trace, failure, or

fixture that gains detail over several disconnected examples. Before a command,

code excerpt, table, transcript, or screenshot, tell the reader what question

it answers; afterward, interpret what matters.

While outlining a mechanism, ask: **What should the reader be able to see that is hard to understand from sentences?** Plan the representation alongside the explanation, using [the visual-language reference](references/visual-language.md). Do not postpone this decision until presentation polish.

Build a private causal outline that connects the starting condition, mechanism,

consequence, evidence, objection, and limitation. Let the selected story mode

determine the public section order. Add a heading when the argument turns, not

because a fixed number of paragraphs elapsed.

## Sound like a thoughtful person

Use plain technical prose: concrete subjects, active verbs, consistent terms,

Preserve what Forge and OverGrid do well: empirical honesty, real limitations,

unfavorable measurements, exact artifacts, and corrected assumptions. Tone

down their recurring AI-shaped habits:

- internal nouns and architecture before the reader knows the concrete system;

- repeated `not X, but Y`, `X is not Y`, and perfectly balanced reversals;

- titles that default to `We`, a product name, a percentage, or a slogan;

- `authority`, `boundary`, `contract`, `receipt`, `durable`, `surface`, and

`exact` used as atmosphere instead of necessary terms;

- uniform triads, bold thesis restatements, symmetrical sections, and compulsory

recaps;

- exhaustive evidence promoted into the main narrative;

- every observation enlarged into a principle and every paragraph polished into

an aphorism;

- a suspiciously clean causal history or a plan narrated as an accomplished

result.

Prefer `the release controller deploys the Worker` to `authority flows through

the release boundary`. Earn one or two memorable sentences by compressing a

true and useful distinction. Do not impose a slogan quota.

## Make artifacts and visuals earn their place

Use small exact code excerpts, focused diffs, authentic screenshots, commands,

measured comparisons, and brief quotations only when they advance the chosen

angle. Give readers prerequisites, expected results, and safe cleanup when

reproducibility is part of the value. Never dump a full transcript or

implementation inventory into the story merely because it exists.

Use a visual when it makes an important relationship easier to inspect or understand. Plan it around timing, topology, data movement, state or a comparison—not decoration. Tables and numbered text boxes are not substitutes for showing those relationships. Separate static explanation, interactive exploration and assessment; rejecting low-value controls is not a reason to omit a useful static diagram. Before

producing or reviewing article visuals, read

[the visual-language reference](references/visual-language.md). Generated

pixels may illustrate an idea but never establish technical evidence. Keep the

central claim available in accessible text.

## Review in three editorial passes

1. **Developmental:** check the angle, belief change, order, deliberate

omissions, strongest objection, elephant in the room, and whether the ending

earns its lesson.

2. **Explanatory:** check assumed knowledge, undefined nouns, jargon, missing

causal steps, the recurring example, artifacts without interpretation, and

concepts introduced too late. Ask whether any central relationship remains

buried in prose and whether each visual actually reveals it. Do not use a

figure quota. In generation pipelines, include this check and the relevant

visual vocabulary in the planning and editorial prompts.

3. **Line:** check concrete verbs, sentence rhythm, noun piles, repeated

antithesis, duplicated conclusions, ordinary proofreading, and title/deck

consequence sentences where they can become easier to remember without

becoming less true.

Factual verification remains a separate evidence check, not a fourth editorial

pass.

Then run a mandatory context-isolated cold read for every standard or feature

post. Give a fresh subagent or uninvolved reader only the draft and public

links—not the task thread, repository history, intended thesis, or angle notes.

Ask:

1. What is this about?

2. What changed, or what is the author arguing?

3. How does the central mechanism work?

4. What evidence supports it?

5. What remains uncertain?

6. Which terms, transitions, or assumed facts block understanding?

Compare the answers with the approved reader beliefs. If the cold reader misses

the subject, thesis, mechanism, or evidence limit, revise and repeat. Fix the

post; do not coach the reviewer. Use the same check in abbreviated form for a

note when confusion risk is high.

## Protect readers and publish deliberately

Remove secrets, credentials, private headers, personal data, customer

identifiers, private paths, and inaccessible links from prose and media.

Distinguish inference from observation. Respect an explicit public or internal

visibility choice; default to public only when the evidence is safe for the

open web.

When the user asks for a finished post, default to carrying it through preview,

commit, push, deployment, and final URL verification unless they request a

draft-only or preview-only handoff. State that intended endpoint in the first

progress update so the user can narrow it. Follow repository instructions and

read [the publishing checklist](references/publishing-checklist.md) before

publication work.

Report source creation, commit, push or merge, deployment, and live verification

as separate facts. Never call a preview, build, health check, or URL alone proof

that the article's technical claim is true.
